Smoke Bush is an interest mountain plant mostly planted in the summer for the flower that hovers above the foliage like smoke rising in the middle of the landscape. This shrub grows tall, reaching 10′ within a few years. It is available in a green and gold variety, but is best-loved for its purple foliage that turns bright orange through fall. Its truly stunning transition is unusual for such a drought-hardy plant. It’s another tall shrub that animals do not like.
